The figure above shows the organization of a protein that will eventually reside in the
plasma membrane. The boxes labeled 1 and 2 represent membrane-spanning
sequences and the arrow represents a site of action of signal peptidase. Which of the
following statements must be TRUE about this protein?
O a) Most of this protein will project from the cytosolic side of the membrane.
O b) The mature version of this protein will span the membrane twice.
c) This is a multi-pass membrane protein.
O d) The mature version of this protein will span the membrane once.
